I was in Lowes, looking at pegboard for the craft closet, and one of the employees rolled a cart of bi-fold doors up front with a clearance sign on them (50% off). Since I am replacing all the doors in the basement, plus the new ones from remodeling, an opportunity presented itself.
Luckily, they were changing door brands, so a lot of stock was put out for fast sale. I ended up buying 10 bi-fold doors and 9 slab doors at half price, saving over $500 - and they all match.
Normally, I buy pre-hung doors, not just slabs, but I had to go this way to match the bi-folds. Part of the challenge of getting things cheap, or reusing things, is making them work. I guess I am going to get good at building door frames and routing hinge mortices...
Normally, I go to Home Depot, but Lowes' selection of things like pegboard is really good. I can say without reservation that their service is terrible, slow and chaotic. I believe the Lowes' management is fully asleep at the wheel on this issue. That being said, when they clearance things out, the prices can't be beat. I just plan (and this case it did indded happen) to stand around for long time waiting for a supervisor to approve the discount sale. I guess mediocre people need to work too.
